FBI FOIPA Addendum 


As referenced in our letter responding to your Freedom of Information/Privacy Acts (FOIPA) request, the FBI FOIPA 
Addendum includes information applicable to your request. Part 1 of the Addendum includes standard responses that apply 
to all requests. Part 2 includes additional standard responses that apply to all requests for records on individuals. Part 3 
includes general information about FBI records. For questions regarding Parts 1,2, or 3, visit the www.fbi.flov/fgjp website 
under “Contact Us.” Previously mentioned appeal and dispute resolution services are also available at the web address. 


Part 1: The standard responses below apply to all requests: 

(i) 5 U S C § 552(c). Congress excluded three categories of law enforcement and national security records from the 
requirements of the F01A [5 U.S.C. § 552(c) (2006 & Supp. IV (2010)]. FBI responses are limited to those records 
subject to the requirements of the FOIA. Additional information about the FBI and the FOIPA can be found on the 
www.fbi.gov/foia w ebsite. 

(ii) National Security/Intelligence Records. The FBI can neither confirm nor deny the existence of national security and 
foreiqn intelligence records pursuant to FOIA exemptions (b)(1), (b)(3), and PA exemption (j)(2) as applicable to requests 
for records about individuals [5 U.S.C. §§ 552/552a (b)(1), (b)(3), and (j)(2); 50 U.S.C § 3024(i)(1)]. The mere 
acknowledgment of the existence or nonexistence of such records is itself a classified fact protected by FOIA exemption 
(b)(1) and/or would reveal intelligence sources, methods, or activities protected by exemption (b)(3) [50 USC § 
3024(i)(1)]. This is a standard response and should not be read to indicate that national security or foreign intelligence 
records do or do not exist. 

Part 2: The standard responses below apply to all requests for records on individuals: 

(i) Requests for Records about any Individual—Watch Lists. The FBI can neither confirm nor deny the existence of 
any individual’s name on a watch list pursuant to FOIA exemption (b)(7)(E) and PA exemption (j)(2) [5 U.S.C. §§ 
552/552a (b)(7)(E), 0(2)]. This is a standard response and should not be read to indicate that watch list records do or 
do not exist. 

(ii) Requests for Records for Incarcerated Individuals. The FBI can neither confirm nor deny the existence of records 
which could reasonably be expected to endanger the life or physical safety of any incarcerated individual pursuant to 
FOIA exemptions (b)(7)(E), (b)(7)(F), and PA exemption (j)(2) [5 U.S.C. §§ 552/552a (b)(7)(E), (b)(7)(F), and (j)(2)]. 
This is a standard response and should not be read to indicate that such records do or do not exist. 


Part 3: General Information: 

(i) Record Searches. The Record/Information Dissemination Section (RIDS) searches for reasonably described records by 
searching those systems or locations where responsive records would reasonably be found. Most requests are satisfied 
by searching the Central Records System (CRS), an extensive system of records consisting of applicant, investigative, 
intelligence, personnel, administrative, and general files compiled and maintained by the FBI in the course of fulfilling its 
dual law enforcement and intelligence mission as well as the performance of agency administrative and personnel 
functions. The CRS spans the entire FBI organization and encompasses the records of FBI Headquarters (FBIHQ), FBI 
Field Offices, and FBI Legal Attach^ Offices (Legats) worldwide. A CRS search includes Electronic Surveillance (ELSUR) 
records. 

(ii) FBI Records. Founded in 1908, the FBI carries out a dual law enforcement and national security mission. As part of 
this dual mission, the FBI creates and maintains records on various subjects; however, the FBI does not maintain records 
on every person, subject, or entity. 

(iii) Requests for Criminal History Records or Rap Sheets. The Criminal Justice Information Services (CJIS) Division 
provides Identity History Summary Checks - often referred to as a criminal history record or rap sheets. These 
criminal history records are not the same as material in an investigative "FBI file.” An Identity History Summary Check 
is a listing of information taken from fingerprint cards and documents submitted to the FBI in connection with arrests, 
federal employment, naturalization, or military service. For a fee, individuals can request a copy of their Identity 
History Summary Check. Forms and directions can be accessed at www.fbi.gov/about-us/ciis/identitv-h isto.ry; 
summary-checks . Additionally, requests can be submitted electronically at www.edo.ciis.gov . For additional 
information, please contact CJIS directly at (304) 625-5590. 

(iv) The National Name Check Program (NNCP). The mission of NNCP is to analyze and report information in response to 
name check requests received from federal agencies, for the purpose of protecting the United States from foreign and 
domestic threats to national security. Please be advised that this is a service provided to other federal agencies. Private 
citizens cannot request a name check.
